Overview

American Diabetes Association Professional Practice Committee. Diabetes Care 2026 · PMID 41358898 · DOI 10.2337/dc26-S005

There is no single diet for diabetes; meals should be individualised with a dietitian, and medicines may need adjustment when the diet changes.

Does the study support the specific claim? Partly · Methodological quality: high

5. Actual results

Results

Full text (PMC12690188, read 2026-10-25): 'there is no one-size-fits-all eating pattern for individuals with diabetes, and meal planning should be individualized'; all people with diabetes should be referred for individualised medical nutrition therapy by a registered dietitian nutritionist. Rec. 5.14 (grade B): eating patterns should emphasise nonstarchy vegetables, whole fruits, legumes, lean proteins, whole grains, nuts and seeds, and low-fat dairy or nondairy alternatives, and minimise red meat, sugar-sweetened beverages, sweets, refined grains, processed and ultraprocessed foods. Very-low-carbohydrate plans need consistent medical oversight; insulin and other diabetes medications may need adjustment to prevent hypoglycaemia; such plans are not currently recommended in pregnancy or lactation, children, kidney disease or disordered eating.

Authors' conclusion

Individualised nutrition therapy under professional supervision is part of diabetes care; several dietary patterns can be appropriate.

Rationale

Guideline with an explicit grading system; not formally appraised here (formal: false).

9. Assessment of the statistical interpretation

Grade B recommendations; no single effect size.

10. Relevance to the specific claim

Agrees with the third-party pages that dietary change in diabetes should be supervised and that medicines may need adjustment; partly conflicts with the Tayebat lists, which exclude legumes, most vegetables and liquid dairy that the guideline recommends, while both advise limiting sugar-sweetened beverages and ultra-processed foods.

11. Independent contrary findings

None.

12. Transferability to Germany and Europe

European guidance (EASD) is broadly similar on individualisation (not audited here).

13. Overall methodological judgement

Authoritative reference for medically supervised nutrition therapy in diabetes.
